MINERS CAP.

Specification of Letters Patent.

)Patented Apr. 24, 1917.,

Application filed December 5, 1916. Serial No. 135,246.

- To all whom t may concer/n:

Be it known that I, LAwsoN MCCLASKY,

a citizen of the United States, residing at' Butte, in the county ofSilverbow and State of Montana, have invented new and usefulImprovements in Miners` Caps, of which the following is a specification.

The present invention contemplates the provision of an attachment forminers caps, comprehending more particularly a lamp supportingbracket,the object of the invention being to provide a simple, inexpensive andeffective device for use upon caps of this character and effectivelypreventing the transmission of current to the wearers body.

Furthermore, it is my object to provide a cap of the above statedcharacter wherein a backing is associated with the bracket proper onwhich the lamp is suspended and having an improved construction ofreinforcement so bent to form a brace or truss, thus preventing theweight of the lamp from breaking the backing at the point of formationof the tongue with the body portion of said backing plate.

lith the above and other objects in view, the invention consists in thenovel features. details of construction and combination of parts whichwill hereinafter be more fully set forth, illustrated in theaccompanying drawing and pointed out in the appended claim.

Figure 1 is a perspective view of a cap showing my attachment assembledtherewith and supporting the usual type of miner`s lamp thereon;

Fig. 2 is a vertical section taken through the bracket; and

Fig. 3 is a detail perspective view lof the backing clearly illustratingthe reinforcing means attached thereto.

With reference to the accompanying drawing, in which like characters ofrefervence refer to correspondlng parts 1n the several views, 5 denotesa miners cap, having secured thereto and disposed in spaced relationwith the `front portion 6 of said cap a lamp bracket, designatedgenerally by the reference character 7. The salient feature of thisinvention and the manner in which the lamp bracket is associated withthe plate, is to avoid the possibility of short circuiting or injuringthe miner by making contact of the metallic portions of the bracket orlamp with current conducting wires, installed in the roof of mines.

To this end, the said bracket 7 consists of identically constructedsections including a backing plate 8 and a supporting plate 9, and asshown the supporting plate is disposed forwardly of and in 4spacedrelation with the body portion 10 of the backing plate 8, when thebracket is applied to the cap. For the purpose of illustration, 1 haveshown the backing plate S bent terminally to provide an upper angularlyarranged lip 11 and a lower lip 12; whereas the supporting plate 9 isbent at right angles to the body portion 13 thereof to provide the sainewith an upper angularly arranged tongue 14 and formed at its other endwith a lower tongue portion 15.

The bracket as an entirety in order to accomplish the function ofpreventing transmission of current to the miners body, is preferablymade entirely of stiff fiber board or other insulating material and thetongue portion 14 of the supporting member overlies the lip l1 `of thebacking plate and is lixedly secured to the peak of the cap, while thelower tongue 15 of the supporting member overlies the lower lip 12 ofthe backing plate. Arranged upon the outer face of the body portion 13of the supportingplate 9 is a spring clip 16 for holding on the bracket7 the miners lamp 1 7, and when the lamp is properly positioned in theclip, the same is supported therein by the engagement of the spur of thelamp Within the opening 18 of an L-shaped clip 19. This L-shaped clip isterminally engaged at one end and fixed to the upper tongue 14 of thesupporting plate, while the opposite end or the vertical portion of thelatter mentioned clip is fixed to the front face of the body portion atthe point of intersection of the upper tongue 14 with the body portion13, this when the lamp is supported upon the bracket, will cause thebreaking or bending of the supporting member, providing no provisionswere made for preventing such. I therefore secure to the oppositelongitudinal edges of the body portion and the-lower lip 12 of thesupporting plate 10, housings 2O having inserted therein spaced parallelreinforcing rods 21, the reinforcing rods 21 being of greater lengththan the housings 20 to provide the same with protruding extremities 22.Secured to the opposite` ings are sleeves 23. The protruding eX`tremities 22 of the reinforcing rods are bent to assume an upward andrearward inclined position, to provide spaced parallel inclined braces24, terminating in straight Shanks 25, the Shanks 25 of said bracesbeing inserted in the sleeves 23, thus holdin the braces to oppositesides of the supporting member l0 at the point ofintersection of theupper tongue portion 14 with the body portion 13, and as before stated,when the weight of the lamp is brought to bear upon the supportingmember 10, these braces will prevent any accidental sagging or breakingof the tongue from the body portion, prolonging the life of the bracket,and further preventing any accidental contact of the metallic members ofthe lamp or bracket in order that a circuit may be completed, thusresulting in the transmission of current to the body of the partywearing the cap.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of construction and the method ofoperation will be readily apparent to those skilled in .the art to whichthe invention relates, and while I have described the principles ofoperation of the invention, together with the device which I nowconsider t0 be the best embodiment thereof, I

desire to have it understood that the ldevice shown is merelyillustrative, and that such changes may be made when desired as arewithin the scope of the appended claim.

What is claimed as new, is

A bracket for supporting miners lamps upon caps comprising a backingplate and a supporting plate, said plates being terminally bent toprovidethe same with an upper tongue and a lower tongue, the saidsupporting plate having its intermediate portion in spaced relation withrespect to the backing plate, lamp supporting means upon said supportingplate at the point of formation of the upper tongue portion with saidsupporting plate, and reinforcing rods attached'to the oppositelongitudinal edges of the supporting plate, said reinforcing rods beingextended beyond the plane of the upper tongue portion, the extendingextremities of said rods being bent to provide braces, said braces lyingon opposite sides of the -point of formation of the upper tongue portionwith the supporting plate, sleeves formed on'the opposite longitudinaledges of the upper tongue of the supporting plate, Shanks formed on thebraces adapted to engage the said sleeves for preventing any accidentalsagging or breaking of the supporting plate, substantially as and forthe purpose specified.

In testimony whereof I affix my signature.
